compose

Overview ¶

compose drives a 2-service devcontainer described by a Docker Compose project: a primary `app` service and a sidecar `db`. The engine starts both services, lets us exec on the primary, and tears the project down at the end.

Requires: Docker daemon + Docker Compose v2 plugin (`docker compose version` must work).

Run:

go run ./examples/compose

What happens:

1. Creates a temp workspace with docker-compose.yml (app + db) and a devcontainer.json pointing at it.
2. Up: the engine loads the compose project via compose-go, generates dc-build.yaml + dc-run.yaml override files, invokes `docker compose up -d`, and resolves the primary service's container.
3. Exec on the primary prints what it sees and confirms the sidecar is reachable on the project network by service name.
4. Down(Remove: true) tears the whole project down.
